摘要

在這畢業論文中分析出傳輸、感測和干擾三種範圍間之關係，並且針對當採取訊號強度控制下，根據三種範圍關係為基礎，提出一個在隨建即連的網路中之訊號強度控制之媒體存取控制協定(ARPC)。因此依據本論文分析，有四種避免資料碰撞的機制，分別是STRC、RTRC、SCRC與RCRC。此外，更進一步的針對上述四種機制推算出各機制合適使用的情況。結合這四種機制的優點，提出一個依據距離關係推算出適當訊號強度控制之媒體存取控制協定。採取上述的協定能有效地避免資料碰撞且達到減少STAs電量消耗。而在最後模擬時也驗證了，所提出的協定能達到上述之優點。

The thesis analyzes the relationships among the transmission range, carrier sensing range, and interference range in case that power control is adopted and proposes an adaptive range-based power control (ARPC) MAC protocol for wireless ad hoc networks to avoid collisions. Based on the analysis results, four mechanisms, STRC, RTRC, SCRC, and RCRC are proposed to prevent from collisions. The thesis further analyzes the superiority of each mechanism under certain situations and proposes an adaptive range-based power control MAC protocol to make use of the advantages of the four mechanisms to avoid collisions for wireless ad hoc network. The proposed protocol can not only reduce energy consumption of STAs, but also prevent from collisions. Simulation results also verify the advantages of the proposed protocol.
